Review on 💾 SanDisk 512GB Ultra Luxe USB 3.1 Flash Drive - High-speed Storage Solution by Alan Lewis

I got 30-50 MB/s at first, but after about the third big transfer the transfer rate was under 10 MB/s, sometimes in the KB/s range. There is no point in using a 128GB USB 3.0 stick if the transfer rate is below USB 2.0 specifications. Ports are fine, drivers are fine - The Seagate external hard drive is ported to the maximum USB 3.0 specification. The Samsung Flash Drive supports data transfer rates of 30-70 MB/s. I regret this purchase.
